Informative Speech On Fossil Fuels

Fossil Fuels Becoming Extinct
Specific purpose: I will inform my audience of how alternate energy sources help protect the environment, different types of energy sources, and the most plausible alternate energy to be used in the future.

Central idea: Alternate Energy sources are being developed to address not only the global effect of fossil fuels on the environment but the ever decreasing quantity of fossil fuels as well.

INTRODUCTION

I. Imagine you are on your way to the gas station for your weekly fill up and you have to wait in line at the gas pumps for up to an hour just to get a tank of gas. No it is not the early 70?s during the ?gas shortage?, however it is a possible scenario in the not so distant future if an alternate
Alternate Energy sources are important to understand based on known oil reserves and the worldwide consumption rate, most estimates suggest this reserve has only 50 more years of production left in it according to AlternateEnergies.com.
III. I first witnessed the high gas prices, as I?m sure all of you have, after September 11, when our country went to war with Iraq.
IV. I thought back to my mother and father in the early 70?s waiting in line for gas, wondering if alternate energy sources had been on the minds of the Department of Energy then the way it is now would high gasoline prices even be an issue.
V. Tonight I would like to inform you as an audience of how alternate energy sources can help protect the environment, different types of energy sources, and the most plausible alternate energy to be used in the future.

(First, let?s look at how alternate energy sources help protect the
Most of the common alternate energy sources are already in use. A. Wind can be harnessed to produce large amounts of energy. Wind energy is very site specific. If you do not have a good wind site to start with, results will be disappointing no matter what you do. B. Solar-Electric (photovoltaic) harnesses the sun?s energy and converts it into electricity. It is the simplest form of alternative energy, it?s also the most expensive. C. Micro-hydro harnesses the energy of falling water and produces electricity. It is the most cost effective of all alternate energy. If you have a source of running water, you simply must harness it?s potential. D. Sometimes more than one alternate energy is combined in a hybrid system to maximize the total energy output. For example, one common design is a wind and solar hybrid system where in the winter months, when the hours of sunshine are low, the winds are generally stronger to make up for it.

(Now that we know about different types of alternate energy sources let?s look at which type will most likely be used to power our cars in the future.)

III. In 2003 President Bush declared a $1.7 billion investment in hydrogen fuel
